The House today approved a bill that would block federal funds from going to Planned Parenthood for one year, unless the organization certifies that it will no longer perform abortions, something that it does not currently use federal funds for.

The vote, driven by a smear campaign from anti-choice extremists, was divided mostly along party lines, with the notable exception of Iowa Republican Rep. Steve King, who voted “present.” In a video statement, King explained that he didn’t think the House bill went far enough in attacking the “diabolical” Planned Parenthood, taking particular issue with the fact that the bill would allow Planned Parenthood to continue offering abortions for women who have survived rape or incest:

The Susan B. Anthony List’s Marjorie Dannenfelser, one of the most influential leaders in the anti-choice movement, held trainings to teach Republican politicians how to change the subject when rape comes up. Dannenfelser has been very clear that she opposes rape exceptions in abortion bans, which she has called “abominable,” “regrettable” and “ intellectually dishonest,” but will urge lawmakers to support a bill that has to contain such exceptions for political reasons.

But hard as Dannenfelser and her allies might try to get anti-choice lawmakers to shut up about rape, they face an uphill battle. Although most anti-choice activists oppose rape exceptions, a vocal portion of the movement believes that lawmakers should automatically reject any bill that includes such exceptions.

A 20-week abortion ban that passed in the House earlier this year and will be coming up for a vote in the Senate next week has been mired for years in anti-choice infighting about rape exceptions. Before a version of the bill came up for a House vote in 2013, Republican leaders scrambled at the last minute to add a rape exception to neutralize controversial comments made by the bill’s sponsor, Rep. Trent Franks.

In January of this year, the House was planning to vote on the bill to mark the anniversary of Roe v. Wade, but scrapped the plan after a coalition led by female Republican lawmakers objected to a provision that would have required rape survivors to report the crime to law enforcement. An exasperated Sen. Lindsey Graham told anti-choice activists the next morning, “I’m going to need your help to find a way out of this definitional problem with rape.”
